Visual Renders - BMX Pump Track and Landscaping

I'm looking to create 3-4 project renders for a a BMX pump track and large dirt jump facilities for recreational use in a park. The project should also include landscaping that uses native plants and trees and overland flow drainage/WSUD solutions.

The park should also feature:
- Benches and seating areas
- shelters
- bike racks
- signage
- pathways and riding features
- lots of bmx riders and people using the space

Ideal skills and experience:
- Experience in constructing BMX tracks, dirt jumps and asphalt pump tracks
- Landscaping with native plants
- Park design and construction

In every case, we would be rendering into an existing drone photograph or normal high resolution photo of the site. NOT using a full model.
Trees and landscape need to look like AUSTRALIA. Not foreign.
Renders need to be atmospheric and excite the viewer. The need to feel like a place you want to visit and something that tells you about the whole project when it is active and in use by the public.

You need to actually be able to sculpt and shape the jumps and riding track features in the design that we have drawn - these would be made from asphalt or dirt

Please provide a portfolio with similar completed projects.
